Abstract

PURPOSE:To provide ease of replacing parts to allow replacing or repairing the parts in a short time period by integrating the operation time period for each of motors that drive equipment of a grain dryer, such as a grain elevator, a valve, a exhaust fan, etc. CONSTITUTION:Motors for a grain elevator 3, valve 6, double speed motor 32, and a moisture sensor 49 of a grain dryer 1 are operated to start the dryer 1, a burner 7 and the moisture sensor 49, and the hot air is generated by the burner 7. The hot air from a hot air chamber 17 passes through a drying compartment 4, and exhausted by an exhaust fan 8 through an exhaust chamber 20, so that the grain fed in the grain dryer 1 is exposed to the hot air while it flows down from a storage bin 12 to the drying chamber 4. The operation time period of each of the motors 3, 6, 9, 32, and 49 of the grain dryer is integrated by an integrator 10 that is individually provided for each of the motors 3, 6, 9, 32, and 49.

Description

[Detailed description of the invention] Industrial applications This invention relates to a grain dryer.

Conventional technology Conventionally, the main components of the grain dryer include a shell raiser motor that rotationally drives a grain raiser that transports grains, a valve motor and burner that rotationally drives a feed valve that feeds and flows down grains in a drying chamber. This grain dryer did not have a totalizing device that separately totals the operating time of the exhaust fan motor that rotates and drives the exhaust fan that sucks and exhausts the generated hot air.

Problems to be Solved by the Invention When the grains stored in the grain dryer are operated, each motor rotates and each part is rotationally driven by operating the operating device that starts the dryer. While flowing down from the storage chamber to the lower drying chamber, the hot air generated from the burner crosses the drying chamber and is sucked and exhausted by the exhaust fan. The grains are transported to the lower part, transported by a rotary wheel, and supplied into the grain raising machine, transported to the upper part of the grain raising machine, and returned to the storage chamber.The circulation is repeated to dry the grains. Ru.

During this grain drying work, when the grain is put into the dryer, the delivery valve and the exhaust fan are not driven to rotate, and the dried grain is removed from the machine. During the discharge work, the exhaust fan is configured so that it is not driven to rotate, and the parts that are driven to rotate differ depending on the work of loading, drying, and discharge, and therefore the durability time set for each part is not accurate. If some parts reached their durability limit during drying work, the drying work could become impossible.

4) A valve motor (6) that rotationally drives a feeding valve (5) that feeds out and flows down the grains inside, and a wind exhaust Im (8) that sucks and exhausts hot air generated from a burner (7). The grain dryer is provided with an integrating device (lO) that integrates the operating time of each of the exhaust fan motors (9) and the like.

Effect of the Invention By operating the operating device of the grain dryer (1), the grain raiser motor (3), valve motor (6), exhaust fan motor (9), etc. of this dryer (1) are activated. Rotating, grain raising machine (
2), the delivery valve (5), the exhaust fan (8), etc. are driven to rotate, this dryer (1) is started, and this dryer (1)
While the grains stored in the storage chamber are flowing down from the upper storage chamber to the lower drying chamber (4), hot air generated from the eight-cell (7) crosses the drying chamber (4) and collects the grains. By suctioning and exhausting the air with the exhaust fan (8), it is exposed to this hot air and dried, and is fed out with the feeding valve (5) and flowed down to the lower part, and transferred with the transfer gutter to the grain raising machine ( 2) The grains are fed into the grain elevator (2), transported to the upper part by this grain hoist (2), and returned to the storage chamber.The circulation is repeated to dry the grains.

Each of the motors (3), (6), and (9) during the loading, drying, and discharging operations of each drying operation,
C6), (9) Different operating times are accumulated in each a calculation device (10) 0 For example, by integrating the operating time of each part, the set durability time of each part is calculated according to this operating time.
